After seeing the title, are you curious why it is called a check valve for current? actually,diodeWith two electrodes, it only allows current to pass in a single direction, so it is used for rectification in many fields. Just like a check valve on a water pipe, water flow can only pass in one direction. Because the two have similar properties, we call it a check valve for current.

In its early days, that isdiodeThe "ancestor" of the world, the vacuum electronic diode, can already perform its function simply. It has unidirectional conductivity of electric current and can form a space charge layer on both sides of it, and the currentdiodeMost of them are made of semiconductor materials. Its one-way conductivity is required in almost all electronic circuits, so it plays an important role in many circuits. Nowadays, it is widely used in electrical appliances, such as TV remote controls and high-speed computers. Even some colorful lights hanging high on high-rise buildings use it to emit a dazzling light that can be seen from dozens of meters away. Even if the external voltage is removed, its performance will be restored well.

Because its performance limitations are very small, people have boldly broadened its use areas. Researchers have conducted extensive thinking and continuous exploration, which has become a major driving force for its widespread use.

In this era when mobile phones are changing very rapidly, people are pursuing the performance of mobile phones even more - "fast", "light" and "beautiful". As people's demands increase, designers use it to optimize the performance of mobile phones to the greatest extent, replacing traditional resistor tubes. This breakthrough has successfully pushed the resistor tubes, which have long been the number one most popular, into the second line.diodeRanked first.

Today's technology is developing rapidly, and with the continuous changes of society, it is no longer rare, and the situation of short supply has been broken, allowing more companies to introduce it into their own products, making it more widely used in various fields, better stabilizing its position as the leader of the industry.
